Study on Support Technology of Gob-side Entry in Stoping Panel of Silaogou Mine

Li Haiqing;Dong Hexiang;  
Based on production geology conditions of the coal pillar of 301 panel in Silaogou Mine of Datong Coal Mine Group, the methods of FLAC3 Dnumerical simulation, field geological investigation and theoretical analysis are integraetly used, surrounding rock deformation law of gob-side entry is analyzed from surrounding rock stress distribution of roadway and surface displacement, the 5 m reasonable coal pillar width is determined, on this basis,the parameters of roadway support are optimized, the purpose of raising resource recovery rate is achieved.
